Abstract

The USGS is partnered with Fort Bragg to meet the water-quality requirements of the upcoming stormwater permit under the Environmental Protection Agency National Pollutant Discharge Elimination System I & II regulations. The USGS has addressed stormwater issues by compiling a comprehensive GIS database. Through GIS, delineated drainage basins and thematic maps have been generated to aid in the characterization of the watershed.

Representative sample sites were chosen from the 154 identified industrial outfalls to evaluate the water quality. Analysis of the data will serve as a baseline in Fort Bragg.s efforts to secure stormwater permits from the State. The USGS partnered with the State of North Carolina to determine and design specific sample locations in order to characterize stormwater contributions to watersheds affected by Fort Bragg. The selected samples represent vehicle maintenance sites, warehouse storage, loading areas with a variety of equipment and other potential polluting materials, as well as temporary storage of hazardous wastes. The data collected from the samples will be reviewed and reported in the annual report of the Stormwater Pollution Prevention Program.
